In a transforming, complex, and innovating telecommunications industry with evolving business models, providers have to resolve how the pricing of their services in a context with many unknowns and few equations. This paper proposes a cost assignment model based on differentiating the set of required services a user consumes in a granular network architecture, to get a requested content. Unlike the flat rate model, this model is focused on obtaining a variable pricing methodology that reflects the actual use of network resources that users utilize to get specific content. There are exploring elements to establish the importance of this topic; the theoretical models of pricing are reviewed, the complexity of the costing issue and the influence of content providers on the real network operating cost are explored. Also, a precise cost model is proposed, as well as some cases of the application of the model in the real world.
